Swiss researchers from the University of Zurich (ETH Zurich) created light-emitting polymers for OLED-displays using photolithography.
Screens are becoming smaller and sharper at the same time. This can be seen, for example, in augmented reality glasses or in electronic searchers of cameras, whose screen diagonal is in part less than one centimeter. The smaller the screen pixels, however, the more difficult the...
Tiny OLED pixels can be manufactured like microchips
Researchers have developed light-emitting polymers that also serve as photoresists and can be precisely patterned using photolithography - an established process in the chip industry. This enables the production of tiny, coloured OLED pixels for screens, as well as precise light sources for research and medical technology.
Researchers develop photoresistive polymer OLED devices based on the core-shell principle
Researchers from ETH Zurich, in collaboration with researchers from RMIT University in Melbourne, developed polymer OLED emitters, that can also serve as photoresists - which means that these materials can be precisely patterned using photolithography. This could open the door to the production of ultra-fine polymer OLED devices. The research explain that they have developed a new class of long-chain (polymer) light-emitting molecules, that can …
